Subspecies
Forms superspecies with Green-breasted Mango (Anthracothorax prevostii) and Veraguas Mango (Anthracothorax veraguensis), and probably also Green-throated Mango (Anthracothorax viridigula). Very closely related to Green-breasted Mango (Anthracothorax prevostii), and occasionally regarded as conspecific, the two evidently replacing each other geographically, with at most very local sympatry in northern Venezuela, south-western Colombia and perhaps elsewhere. Subspecies iridescens of Green-breasted Mango (Anthracothorax prevostii) has alternatively been attributed to present species.
